Lady GaGa is teaming up with Giorgio Armani for her world tour.

The Italian designer has created some bespoke costumes for the 'Monster Ball' concerts, which will stay true to the 'Poker Face' singer's eccentric style.

In a statement, the fashion house said: "We hear Lady Gaga's music everywhere we go, it is like a soundtrack of our times. In addition to her formidable songwriting skills, she is a modern fashion phenomenon."

One of the outfits is a stunning hooded one-piece with a lobster-like effect on one sleeve while another is a sparkly blue body suit with pointed shoulders.

Gaga recently revealed she felt "honoured" when Armani agreed to dress her for the Grammy Awards.

They created custom pieces for her to wear on the red carpet and during her performance at last month's prestigious ceremony, including a lilac and silver space age, solar system-inspired stiff-skirted gown.

She said: "I am honoured to be wearing Armani this evening. The series of pieces Mr. Armani created for me are truly iconic; they represent not only beautiful fashion, but my spirit and essence as an artist. Mr. Armani is a fashion legend, and tonight would not have been the same without his touch, and his wonderful team."
